概括

这项研究确定了关键的基因乙化相关基因 (HARG),可以预测尤文肉瘤 (EWS) 患者的生存率. 一个新的基因特征准确地预测了预后,并揭示了不同的分子途径,突出显示了HDAC2作为潜在的瘤基因.

科学领域:

表观遗传学在表观遗传学中,表观遗传学是指表观遗传学.
癌症生物学癌症生物学
基因组学就是基因组学.

背景情况:

基因组乙化是影响瘤发育的关键表观遗传机制.
结核素乙化相关基因 (HARGs) 在尤文肉瘤 (EWS) 中的预后意义和功能作用基本上是未知的.
了解EWS中的HARG对于开发向疗法和改善患者治疗结果至关重要.

研究的目的:

调查HARG在EWS中的预后值和潜在功能.
根据HARGs开发一种基因特征,以预测EWS患者的存活率.

使用考克斯回归和最小绝对收缩和选择操作员 (LASSO) 回归来构建预后基因特征.
在外部EWS队列中验证了签名,并通过沉默HDAC2表达进行了体外实验.

主要成果:

研究人员开发了一种由四个基因组成的特征 (TAF4,ATF2,HDAC2,OGA),可以准确预测EWS患者的存活率 (AUC值在0.833到0.909之间).
患者被分为低风险和高风险组,高风险得分与糟糕的生存结果相关 (p < 0.001).
在风险组之间确定了不同的功能和免疫相关途径,沉默HDAC2抑制了EWS细胞活力和迁移.

结论:

这项研究确定了HARG在EWS中的预后价值,并引入了强大的预测基因签名.

Histone Modification

Histone Modification

The histone proteins have a flexible N-terminal tail extending out from the nucleosome. These histone tails are often subjected to post-translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination. Particular combinations of these modifications form “histone codes” that influence the chromatin folding and tissue-specific gene expression.
Acetylation
The enzyme histone acetyltransferase adds acetyl group to the histones. Another enzyme, histone...

lncRNA - Long Non-coding RNAs

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...
